MEANS FOR ATTACHING SPURS T0 TRACTION-WHEELS.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed April 21, 1919. Serial No. 291,424.

To all whom it may concern Be it known that I, HARVEY R. KIDNEY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Means for Attaching Spurs to Traction-Wheels, of which the following is a specification.

This invention relates to traction-wheels, especially those designed for use on tractors; and it has particular reference to means for attaching spurs to the rim of the wheel.

In tractors employed by farmers'for general use, it has been found desirable to provide for detachable spurs in the tractionwheel construction, and the primary object of the present invention is the provision of means whereby the said spurs may be readily and conveniently attached to and detached from a wheel. The invention provides further, for a single or unitary connecting member for the attachment of a plurality of spurs, the connecting attachment device being wholly within the wheel and being of simple, durable and reliable construction; easy and convenient to operate, and highly eflicient in its function.

l/Vith these objects in view, the invention consists in the construction, combination and arrangement of the parts as hereinafter described and pointed out definitely in the claim, reference being had to the accompanying drawing which is made a part of the specification, similar reference characters being employed to designate corresponding parts.

In the said drawing Figure 1 represents a traction-wheel in elevation with the spokes broken away, and illustrating an embodiment of the invention.

Fig. 2 is a face View of a wheel with the spurs attached.

Fig. 3 is a fragmentary view, enlarged, and showing a portion of the wheel-rim and one spur member in section.

4 is a plan view of one of the attachments, and a fragment of the locking connection, and Fig. 5 is a section on line 5-5 of Fig. 8, with the locking device eliminated.

Fig. 6 is a fragmentary view of a modified form, and Fig. 7 is a view of one of the modified spurs, detached.

Fig. 8 illustrates another modification.

In the preferred embodiment of my in vention, as illustrated in Figs. 1 to 5, inclusive, I have employed spurs of angle formation, the flange 1 of a spur unit, being adapted to lit the outer periphery of the rim 2, and extending transversely on said rim, the flange l forming the traction member when the spurs are attached to the rim.

The flange l is provided with dowels 1*, best shown in Fig. 5. These dowels register with apertures provided therefor in the rim 2. An aperture 1 is also provided in each spur unit, and these apertures register with corresponding openings 2 spaced in the rim 2 to accommodate the desired number of spurs.

Attachment members 3 are provided, equal in number to the number of spurs used. Each of the members 3 comprises a hooked finger 3 adapted to pass through the registering apertures 1 and 2, a shoulder 3 and an arm 3 The arm 3 is provided with an offset hook 3.

By referring to Fig. 5, it will be noted that the transverse dimensions of the openings 1 and 2 are suflicient to allow the passage therethrough of the head of the hook member 3*, when the member 3 is turned at right angles to the position shown, and to permit the shank of the hook to be turned to its gripping position, or with the ledge 3 bearing on the flange 1.

In operation the spur members are placed on the outer periphery of the wheel-rim, being properly positioned through the medium of the dowels 1 seating in the apertures provided therefor in said rim. The members 3 are then applied, the hooks 3 being inserted from the interior of the wheel, through the openings 2 and 1, and turned until the ledge 3 is over the flange 1. This primary stage of the operation retains the spur members loosely in position on the rim 2. A. flexible member, preferably a steel wire cable 4 is provided. The said member a is engaged by the hooks 3, and has its terminals connected by a turn-buckle 5. After the member 4- has been placed in engagement with the hooks 3 it is drawn taut by the turn-buckle 5, which operation causes the member 3 to fulcrum on the shoulder 3 and the ledge 3 to bind on the flange 1, thereby firmly locking the plurality of spurs to the wheel-rim.

An obvious advantageous feature of the invention is the connection of a plurality of spurs with the binding member 4 provided with the simple adjustment element 5,

whereby all of the spurs can be conveniently and quickly attached or detached.

In the modification illustrated in Figs. 6 and 7, substantially the same principle is involved. The member 4 engaging the hooks 30 which are attached direct 'to the spur members 31, and being drawn taut by the turn-buckle 5, causes said spur members to bind on the rim 2.

In the modification shown in Fig. 8, a hook 31 is provided with a head 31, and is adapted for engagement with the member l.

It will be understood that I am not confined t0 the specific design as shown, but that there may be various changes in details of construction without departure from the spirit of the invention, or the scope of the appended claim.

What I claim and desire to secure by Letters Patent is.

Means for attaching traction spurs to a wheel-rim, said means comprising the combination with the wheel-rim and spur members, 01": a flexible tension device; means connected With the spur members, extending through the wheel-rim, and engaging the flexible tension device; and means for tightening the tension device in its engagement with the spur connection, whereby the spur members are firmly seated on the periphery of the wheel-rim.

In testimony whereof I afiiX my signature.

HARVEY R. KIDNEY.
